On the Privacy Practices of Just Plain Sites
In addition to visiting high profile sites such as Facebook and Google, web
users often visit more modest sites, such as those operated by bloggers, or by
local organizations such as schools. Such sites, which we call "Just Plain
Sites" (JPSs) are likely to inadvertently represent greater privacy risks than
high profile sites by virtue of being unable to afford privacy expertise. To
assess the prevalence of the privacy risks to which JPSs may inadvertently be
exposing their visitors, we analyzed a number of easily observed privacy
practices of such sites. We found that many JPSs collect a great deal of
information from their visitors, share a great deal of information about their
visitors with third parties, permit a great deal of tracking of their visitors,
and use deprecated or unsafe security practices. Our goal in this work is not
to scold JPS operators, but to raise awareness of these facts among both JPS
operators and visitors, possibly encouraging the operators of such sites to
take greater care in their implementations, and visitors to take greater care
in how, when, and what they share.Comment: 10 pages, 7 figures, 6 tables, 5 authors, and a partridge in a pear

A review paper on preserving privacy in mobile environments
Technology is improving day-by-day and so is the usage of mobile devices. Every activity that would involve manual and paper transactions can now be completed in seconds using your fingertips. On one hand, life has become fairly convenient with the help of mobile devices, whereas on the other hand security of the data and the transactions occurring in the process have been under continuous threat. This paper, re-evaluates the different policies and procedures used for preserving the privacy of sensitive data and device location.. Policy languages have been very vital in the mobile environments as they can be extended/used significantly for sending/receiving any data. In the mobile environment users always go to service providers to access various services. Hence, communications between the service providers and mobile handsets needs to be secured. Also, the data access control needs to be in place. A section of this paper will review the communication paths and channels and their related access criteria. This paper is a contribution to the mobile domain, showing the possible attacks related to privacy and the various mechanisms used to preserve the end-user privacy. In addition, it also gives acomparison of the different privacy preserving methods in mobile environments to provide guidance to the readers. Finally, the paper summarises future research challenges in the area of privacy preservation. This paper examines the ‘where’ problem and in particular, examines tradeoffs between enforcing location security at a device vs. enforcing location security at an edge location server. This paper also sketches an implementation of location security solution at both the device and the edge location server and presents detailed experiments using real mobility and user profile data sets collected from multiple data sources (taxicabs, Smartphones)
